Invoking ICU from Adobe AIR Applications (Part 2): using Flash Builder 4.6

This article was originally written in English. Text in other languages was provided by machine translation.

In my previous blog article http://blogs.adobe.com/globalization/invoking-icu-from-adobe-air-applications-2, I demonstrated using the AIR3 ActionScript Native Extensions feature to invoke ICU from an AIR application. I used the AIR developer tools to compile and build various components. In this article, I demonstrate the same using the prerelease version of Adobe Flash Builder 4.6. It is much simpler to do this in Flash Builder avoiding the cumbersome command line.

The prerelease version of Adobe Flash Builder4.6 has a new Flex SDK version 4.5.2, which has AIR3 integrated. Please download the sample files as follows.

You will need the following software to build an ICU extension for AIR platform.

1         Building ICU extension for Adobe AIR

Adobe AIR t native extensions, also known as ‘ane’ or ‘ANE’ files are archived packages. These consist of

  • ActionScript wrapper classes calling into external DLLs
  • The external DLLs
  • XML file describing details of external DLLs

The archived ANE files are used just like SWC libraries in integrating into an AIR application. In other words, ANE file is a library and it has public ActionScript APIs.

Covering all details about the ActionScript extension is too much for this blog article, but I will explain the steps to build this sample and run. Below are the sequential steps and commands.

1.1       Building Windows AIR ICU Extension DLL

1)      The AirIcuExtensionWin folder has the Visual studio solution ‘AirIcuExtension.sln’. Open this in MS VS2010.

2)      The file AIRIcuExtension.cpp has the necessary code needed to interface with Adobe AIR 3. It also has the wrapper routines calling ICU C functions.

3)      This is a DLL project and the build output is AirIcuExtension.dll

1.2       Building ActionScript Library in FB 4.6

1.2.1       Building the ActionScript library

Create a new ActionScript Library project and name it AirIcuExtension. See the downloaded ActionScript FB4.6 library project.

1.2.2       Packaging ActionScript native extension

To package an ANE, you still need to do it in commandline. FB 4.6 does not have a feature yet to generate ANEs in the IDE.

Open the binAirIcuExtension.swc is a zipped archive. Open it using WinRAR or WinZip program and extract the library.swf file in the swc package into the AirIcuExtensionbin folder.

The folder srcresources contains file extension.xml, AirIcuExtension.dll and ICU dlls icudt48.dll, icuuc48.dll, icuio48.dll and icuin48.dll. The file external.xml defines the external library details to AIR runtime.

For simplicity, place the AirIcuExtension.dll, ICU dlls and extension.xml files in AirIcuExtensionbin folder. All these files are packaged into a zipped archive called AiricuExtension.ane using the following command.

C:FB4.6sdksbinadt -package -storetype pkcs12 -storepass <passwd> –keystore <AIR certificate> -tsa none -target ane AirIcuExtension.ane extension.xml -swc AirIcuExtension.swc -platform Windows-x86 library.swf AirIcuExtension.dll icudt48.dll icuin48.dll icuio48.dll icuuc48.dll

Using Adobe FlashBuilder4.6 or  C:FB4.6sdksbinadt program, one can generate an AIR certificate.

The output is an archive file AirIcuExtension.ane in the AirIcuExtensionbin folder.

1.3       Building the Test program AirIcuExtensionTest.mxml

Now that we built and packaged the native extension package AiricuExtension.ane, we are ready to use this and call ICU services in a test program.

The folder AirIcuExtensionTestsrc contains the test file AirIcuExtensionTest.mxml. The descriptor file AirIcuExtensionTest-app.xml has  the details of native extension.

Flash builder4.6 has a new feature to link Flash applications with ANE files. As you see from the FB4.6 project properties ‘Flex Build Path’ command, there is a new tab for Native Extensions. Using ‘Add ANE’ button, add the AirIcuExtension.ane file present in the AirIcuExtension/bin folder as shown below.

Also see the ‘Flex Building Package’ command in the project properties, there is a new tab for Native Extension. Please make sure that the check box for AiricuExtension is On.

The output swf file AirIcuExtensionTest.swf is placed in the bin-debug folder.

1.4       Building AIR package for executing AirIcuExtensionTest

The final step is to package the above AirIcuExtensionTest .swf and AirIcuExtension.ane files into an AIR executable folder.  We can do this in FB4.6 now instead of using tedious command line.

  • IN FB4.6, select AiricuExtensionProject and execute menu command Project->Export Release Build…
  • In the ensuing dialog, choose Signed native installer radio button. We can only create native installers as we are using OS specific ANE package.
  • In the Native Extensions tab, make sure that the AirIcuExtension.ane checkbox is On.
  • Finish creating the release build after entering the correct AIR certificate credentials.

The output of the above command is an installer AirIcuExtensionTest.exe. By executing it, you can install the test program.

2         Conclusion

The sample illustrated how to invoke ICU from ActionScript. The AIR ICU extension is easy to build using the upcoming AdobeFlash Builder 4.6 release. ANE is a great feature for AIR developers and AIR applications can make use of the platform or ICU provided globalization services.

Format date and time in non-Gregorian calendars

Although the Gregorian calendar is the most used civil calendar, there are other calendars used in different countries and regions.

Islamic calendar is used in many Islamic countries and it has quite a few variances. Japan uses the imperial calendar which identify the year with an era name(年号, nengō) and a number. Thailand uses a calendar that counts in the Buddhist era.

With flash.globalization package, you can easier format a date in non-Gregorian calendars. See the code below.

Adobe’s Latin American user communities show off their talent and passion

Recently I had the opportunity to attend two events organized by Adobe users in South America: Adobe En Vivo and Flash Camp Brasil.

Adobe En Vivo (Buenos Aires, Argentina)http://www.adobenvivo.com/argentina2011

Now in its fourth edition, “Adobe En Vivo” (‘Adobe Live’) was organized by Maximiliano Firtman and Mariano Carrizo, co-managers of ARFUG (Argentina RIA and Flex User Group). Hosted in beautiful Buenos Aires (Argentina), this well-attended event was targeted at Spanish-speaking developers and designers using Adobe’s tools and technologies in these regions.

Most event sessions focused on mobile development. Presentations covered topics such as how to get started with mobile development, game development, 3D development, multiscreen development, monetization, as well as content creation and management using Adobe tools. Most speakers were managers of Adobe user groups from throughout Latin America and Spain.

I had the pleasure of meeting and socializing with most of the event speakers. I was impressed by their mastery of Adobe tools and technologies, their presentation skills, and overall, their ability to work together in raising the profile of the Spanish-speaking Latin American community of Adobe users. This must be no easy feat, given that they come from 8 different countries.

Flash Camp Brasil (Maceió) – http://flashcampbrasil.com.br

Once again, beautiful Maceió, located in the tropical state of Alagoas in Northeast Brazil, hosted Flash Camp Brasil, a professionally-organized event led by Demian Borba, CEO of Action Creations and manager of the Jornada Adobe Brasil user group.

Some big industry names, from both Brazil and abroad, shared their expertise with the crowds here. This highly-publicized conference attracted many professionals from throughout Brazil, and featured sponsor stands, professional video makers and photographers, a user group stand, and even a space for attendees to unwind and play videogames.

I had the privilege to meet many Adobe Brazilian users, and I was impressed by their passion for Adobe and its products, and their energy. Also, I was surprised by a last-minute invitation to join John Koch in delivering the welcome keynote to an audience of aprox. 500, which proved to be an exciting experience.

If you haven’t attended one of these user-organized events yet, you should definitively consider it. It’s not only a great place to learn, but also to meet and network with industry peers. Check out Adobe’s groups site for the user group of interest nearest you, there you will find information about upcoming events.

I also want to acknowledge the great work by John Koch, Adobe Community Manager for Latin America and Asia, who invited me to these events, and who gives these communities enormous support and encouragement.

How to create a localized DateChooser in your Flex app

This article was originally written in English. Text in other languages was provided by machine translation.

By default the DateChooser in Flex shows the English UI. You need to set the dayNames and monthNames properties to localized strings so that it shows the language you want. But do you know that all these localized names are available in the flash.globalization package? Here’s how to get the localized names.

First, create a DateTimeFormatter object with the locale you are interested in the <fx:Script> section

Alternatively, if you feel more comfortable with MXML than ActionScript, you can use a MXML DateTimeFormatter in the <fx:Declarations> section.

Second, create a vectorToArray function for type conversion in the <fx:Script> section, we will explain a little more in the next step.

Third, in your <mx:DateChooser> component, set the dayNames and monthNames properties.


And since you are using the DateTimeNameStyle enums, you want to import them in <fx:Script>

Here, the getWeekdayNames and getMonthNames methods give the localized names as a vector of string. And vectorToArray function is used to convert them to array before assigning them to the DateChooser. The getFirstWeekday method gives the first day of the week for the locale. For example, many european locales use Monday as the first day instead of Sunday.

That’s it. Now run your app and you will see the DateChooser UI is showing in Chinese.

Change the locale to British English (en-GB) and Arabic, Saudi Arabia (ar-SA) to see how the locale changes the first day of week.

Think that this doesn’t save time than hardcoding? Such as:

It is true if you just need to localized to your language. But imagine you need to localize in multiple languages, or languages you don’t know, or you want language switchable by users at run time. Using flash.globalization is more scalable.

To learn more features provided by flash.globalization package, check out the ActionScript API documentation.
